Since finishing up a rehab program, Demi Lovato has been spotted out and about with ex-boyfriend Wilmer Valderrama, according to Us Magazine.

Lovato, who pulled out of the 'Camp Rock 2' tour last fall to "seek medical treatment for emotional and physical issues," has been seen meeting up with the former 'That '70s Show' star all over LA.

According to one insider, Lovato, 18, and Valderrama, 31, have been quietly dating since Lovato's split from Joe Jonas last May.

While her rep has declined to comment on her client's personal life, Perez Hilton claims the couple have been shopping for groceries together and looking generally "affectionate" with each other.
